Iran digging in with underground nuke facilities expansion

Telegraph:

Iran has expanded its underground nuclear facilities and covered them with a 25ft protective layer of earth and concrete, it has been claimed.

David Albright, a former United Nations weapons inspector who now works for the Institute for Science and International Security in Washington, studied commercially available satellite images taken over a four-year period up to January this year.

His conclusion was that the images showed that the Iranians were developing nuclear facilities, built underground to protect them from possible air strikes. The newly discovered work "is indicative of a new underground facility or further expansion of the existing one", he said.

Mr Albright reported that the pictures showed considerable work on two huge fuel enrichment halls at Natanz, about 180 miles south of Teheran. Each structure is about 480ft by 510ft.

"Both cascade halls have been covered in dirt. Trucks and steamrollers are laying what appears to be a grey material, possibly cement, over the soil," the report states. Three more layers are then shown being placed over the first. Cascades, a series of centrifuges, are used to enrich uranium, which could be used in a nuclear bomb.

Why hide work on a "peaceful" project?
